Released in December 2010 this puzzle is part of series of eight variants, all named after the eight planets of the solar system. After the "Crazy 3x3x3 Plus"-series this is the second series with eight variants named after the solar system. The symbols used for the megaminx are identical to the predecessor. They even show a square faces instead of a pentagon.

At first all varaints look identical to the Crazy Megaminx aka Circle Megaminx but the differences become visible when the variants are mixed up: On some sides the pieces within the circles move together with the surrounding layer, on others they do not. These differences are achieved with different face pieces connected to cores identical to every varaint.With twelve sides there are 2^12=4096 possible configurations. Without symmetric duplicates there are 82 variants left. One variant is the traditional Megaminx (ALL circles turn together with the surrounding layer) and one layer is the Circle megaminx. Of the remaining 80 variants* 8 have no symmetries at all.* 42 have one symmetry.* 12 have three symmetries.The 8 implemented variants were choosen from the 18 remaining variants with more symmetries.

Mercury is the inverted variant of Jupiter.Earth is the inverted variant of Uranus".Mars is he inverted variant of Neptune".Saturn is its own inversion.Venus' inverted variant is not in the series and has the lowest degree of symmetry of all implemented variants. Venus must have been choosen because because all remaining ones with many symmetries were considered to be trivial (to similar to the traditional megaminx or the pure Crazy Megaminx) or to similar to the other seven variants.

All eight variants come with an identical color scheme out of solidly colored plastic pieces (without stickers) and an uniform package. The eight variants can be distinguished from the outside by the symbol (and name) on the white center piece.

In the variant "Neptune" six circles (forming a single ring) move together with the surrounding layer.
